● Use

FGNC-XD-type lightning Insulator Clamp string suitable for overhead distribution lines, the overhead insulated wire or bare wire is fixed on the sheet resistance to the corner bar or rod insulators, thereby fixing the overhead wires and taut; and overhead insulated wire or bare wires in the corner tension rods or rod fittings, thereby tightening the overhead wires and insulation resistance Zhang; provided with lightning ignition device, play the role of lightning.



●Outline
                    Due to global weather changes, often thunderstorms inclement weather, thunder and lightning weather more frequently, with the resulting grid failure accounted for 35.8% of the entire line failure, and in which the insulation off the sheet lightning rate of distribution lines accounted for 96.8 %, greatly affected the normal power line networks, causing losses to the national economy is also very serious, the current distribution lines lightning has caused considerable attention. 

This product is set to prevent breakage and prevent lightning damage insulator function, examine the electrical grounding function, self-locking wedge Tension clamp fixing and suspension functions lightning conductor pull holding insulator Clamp string. Its structure is reasonably new, simplified tension string and lightning protection devices, reducing the failure point, as one set of versatile, easy construction, energy efficient, attractive, long life, clip selection of interchangeable, easy procurement selection, and can be done throughout the insulated distribution function. Is a comprehensive upgrade of power lines and equipment replacement product.
